![]() B) A separate ground buss to carry the circuit ground patterned after our point-to-point amplifiers to streamline the signal path. In a point-to-point wired circuit the heater wires would be twisted together and run a close to a metal chassis as possible. ![]() One leg of the 6.3 Volts AC is run on the top side of the board while the other leg is run exactly below it on the bottom side. Some features of the board include: A) Self-canceling AC heater layout feeding pins 4 and 5 on each tube. B) Mounted on a piece of wood, the parts including tube sockets and volume control are mounted on the top side where there is no silk screened parts layout. Parts can placed on either side of the board depending on how the board is mounted: A) Mounted inside a steel chassis parts (not tube sockets or volume control) are mounted on the bottom side with the silk screened parts layout. The tube sockets mount to the top side of the board only. The silk screen is printed on the bottom side of the board. ![]() The see-thru picture below lets you see the traces on both sides of the board at the same time.ģ DECWARE / HIGH FIDELITY ENGINEERING CO. ![]() MOUNTING THE CIRCUIT BOARD Objective The circuit board has been designed to be used in 2 ways A) Mounted on stand-offs to a piece of wood and B) Mounted on stand-offs inside a metal chassis. 2 DECWARE / HIGH FIDELITY ENGINEERING CO. ![]()
